Coffee lovers rejoice — because a new book claims your daily cup of coffee can have serious benefits for your health — and assist in reducing your waistline.

In “The Coffee Lover’s Diet,” journalist and health expert Bob Arnot explores how a cup of coffee can help with weight loss by increasing metabolism, alleviate the effects of fatty foods and even cause a consumer to burn more calories than someone who abstains.

“You’re going to burn 100 more calories a day by drinking coffee than if you haven’t.”

“Second, if you have coffee before your workout, you’re burning many more free fatty acids.”

The premise of the diet claims that coffee burns fat, suppresses the appetite and speeds up metabolism.

Combined with a sensible eating plan, the diet says that consumers should drink hot, black coffee right after each meal, before bathing and just before exercising.

Nutritionist Kristen Beck told News.com.au that while coffee can boost metabolism, the effects are usually short lived.

“Caffeine can boost athletic performance, both in terms of measurable exercise outcomes such as speed, power and endurance, as well as psychological benefits in terms of making exercise seem more achievable,” Beck explained.

“Coffee can suppress appetite simply by providing a boost of energy, but relying on coffee as a source of energy is that it is only short term.”

Alex Hodge, a gastroenterologist and liver disease specialist at Monash Health, the largest public health service in Melbourne, Australia told the Herald Sun that “coffee, overall, is good for you” as it has been associated with a string of health benefits.

“Drinking coffee has also been associated with fewer incidents of neurodegenerative conditions like Parkinson’s disease and Alzheimer’s disease, with a lower risk of developing type 2 diabetes,” he said.

“There’s limited but emerging evidence that coffee is associated with lowering the risk of several cancers including colorectal, liver, ovarian, pancreatic, esophageal and endometrial. It has all those beneficial associations.”

Arnot explained that the consumption of coffee had a positive impact on how the body broke down fat.

“Coffee at the end of a big fatty meal decreases the amount of fat that’s absorbed and decreases the amount of sugar that’s absorbed,” says Arnot.

“If you give somebody a high-fat meal, their vascular function deteriorates, which over time can be a great risk. With a very high-phenol coffee, we blunted that response and actually improved vascular function.”

Beck, who admits to drinking three cups a day, said people need to be aware that the use of coffee is like the spark plug in a car — “you still need the gas to keep you going.”

She said that while coffee does have proven health benefits, people shouldn’t take that to mean that they can have unlimited lattes.

“If you don’t already drink coffee, I would not encourage you to start in pursuit of weight loss,” she said.

“The thing to bear in mind here is that this diet is not just about drinking coffee, it also has an accompanying healthy eating regimen that, no doubt, is responsible for the vast majority of any weight loss achieved.”

“You need to think about how you drink your coffee. A latte with sugar is almost a small meal in itself, though not a healthy one.”
